Recent evidence suggests that Brazilian Cerrado has been largely converted, mainly due to agribusiness activities and urbanization. Thus, the present work aimed to obtain the diagnosis of a watershed characterized by the expansion of sugar cane fields in the Brazilian Cerrado (Southeastern), employing integrity landscape indicators (Hemeroby, Urbanity Index, Landscape Vulnerability Index, and Water Quality Index) to verify the landscape naturalness, and the consequences of these actions to the ecosystem services provision. Remote sensing data for the years 1998, 2008, and 2018 were employed to verify the land-use changes in the Feijão River watershed (southeastern Brazil), as well as a matrix that considers the land use typologies and their capability to provide ecosystem services. The study area is classified as mixed land use, with the main categories related to agribusiness (sugar cane, pasture, bare soil). The Hemeroby and Urban Index denote naturalness declines over the years, and the observed patterns negatively impact ecosystem service provision. Landscape Vulnerability Index and Water Quality Index demonstrated that remaining vegetation cannot effectively retain pollutants, and severe impairments in the resilience of natural components of key ecosystem service providers (i.e. water and native vegetation) were observed. The results allowed the identification of priority areas for recovery and the maintenance of ecosystem services in agricultural lands.

The concern of the ethics and the meaning of life in young adults became universal and are present in all contexts of human life. Such universality is due to the development of modern rationality, to establish a relationship between the intrinsic theoretical dimensions (scientific) and practical dimensions (ethical), originated that are present in the own array of knowledge. This descriptive cross-sectional study, aims to identify the values of the ethical dimension and meaning of life defended by the college students of the Universities of Madeira, Portugal and Fortaleza, Brazil. The sample consists of 605 University students (Madeira = 225 and Fortaleza = 380), with an average age of 21 years and a standard deviation of 2. We used the questionnaire on values (adapted from the European Values Survey). Most of the young people referred to have a religion (60% wood and 78.4% stronghold), being the most Catholic, however, present in your frequency disinterest and, yet, in Brazil there is a greater diversity of religions. Supporting the intervention of religious institutions in situations of everyday life is accepted mostly by Brazilians, with the exception of politics (35.5%). On the other hand, the university students of the University of Madeira understand that Religious Institutions should only give their opinion on racial discrimination (76.6%). Believe in God (90.8% and 55.1% Stronghold) and Soul (80.3% and 66.4% Stronghold) are beliefs more referred to by college students. These results are intended to contribute in the field of research on ethical values and meaning of life in young people. This study contributes to future comparative research among university students and to developing strategic programs in education and health, increasing the success and excellence in the formation of a full citizenship, preventing the fanaticisms and the social discrimination that today devastate the collective globally.

引用

Open Journal of Veterinary Medicine 2015年第2期5卷 19-24页

作者： Breno Barros de Santana Tallys leandro Barbosa da silva Rafael Antonio Nascimento Ramos Leucio Camara Alves Gílcia Aparecida de Carvalho Unidade Acadêmica de Garanhuns Universidade Federal Rural de Pernambuco Garanhuns Brazil Departamento de Medicina Veterinária Universidade Federal Rural de Pernambuco Recife Brazil Dipartimento di Medicina Veterinaria Università degli Studi di Bari Bari Italy

Intestinal nematodes are among the most common parasites of dogs, being Toxocara spp. and Ancylostoma spp. threats to public health due to their zoonotic potential. In this study, three parasitological diagnostic techniques for detecting the eggs/oocysts of canine intestinal parasites were evaluated. Fecal samples (n = 285) were collected from the environment (i.e. public streets, squares and homes) in Garanhuns, Pernambuco, Brazil. Samples were analyzed using the Willis-Mollay simple flotation technique, spontaneous sedimentation (Hoffman, Pons and Janer) and modified centrifugal flotation. Among the samples analyzed, 56.49% (161/285) showed eggs and/or oocysts of intestinal parasites. In particular, 44.21% (126/285) were detected by the Willis technique, 45.14% (121/268) by centrifugal flotation and 31.57% (90/285) by the Hoffmann technique. The kappa index indicated good concordance between the centrifugal flotation and Willis techniques (κ = 0.625), whereas fair concordance was observed between Hoffmann and Willis (κ = 0.480), and between Hoffman and centrifugal flotation (κ = 0.433). In conclusion, the centrifugal flotation technique showed high sensitivity towards detecting Ancylostoma spp. and Toxocara spp. (the most common parasites in this study) and could be used in association with the Willis technique to obtain safe diagnoses within routine laboratory analysis.

引用

Journal of Pharmacy and Pharmacology 2018年第3期6卷 254-258页

作者： Ludmila Resende Guedes Silas Castro de Carvalho Vitor Nunes Arantes Arthur Manoel Braga de Albuquerque Gomes daniel Antonio de Albuquerque Terra Nathalia da silva Braga Nicoly Eudes da silva dias Endoscopy Unit of Alfa Institute of Gastroenterology at Hospital das Clinicas da Universidade Federal de Minas Gerais (UFMG) Belo Horizonte MG 30130100 Brazil

Introduction： Gastrointestinal Dieulafoy＇s lesion is a rare entity, of unknown etiology, and corresponds to an arterial malformation at the submucosal space that can be a source of life-threatening hemorrhage. We report a case of a Cecum Dieulafoy＇s bleeding lesion that was managed endoscopically with a favorable outcome. Case report： Female, 70-year-old, diagnosed with type 2 diabetes, hypothyroidism, and chronic heart failure associated with rheumatic mitral stenosis, submitted to biological valve replacement in 2006 and with permanent atrial fibrillation using vitamin K antagonist anticoagulant for thrombosis prophylaxis. Her background includes a stroke in 2004 without any permanent disability. In 2016, the patient experienced voluptuous and painless lower gastrointestinal bleeding with severe acute anemia, requiring hospital admission, fluid resuscitation and blood transfusion. Urgent colonoscopy revealed a small reddish vascular malformation at the cecum with oozing active bleeding, about 3 mm in size. Initially argon plasma coagulation was performed with satisfactory and immediate hemostasis. One week later, she recurred with hematochezia. The lesion at the cecum was reassessed and it was possible to notice a large caliber vessel surrounded by a normal appearance mucosa, compatible with Dieulafoy＇s lesion and it was treated with an endoscopic clip placement with a good long-term response. Conclusion： Endoscopy is the method of choice for diagnosis of Dieulafuy＇s lesion and may provide efficient treatment with mechanical hemostasis such as endoclip placement with a high success rate.

Electrochemical Remediation of 17α-Ethinylestradiol

引用

Journal of Chemistry and Chemical Engineering 2013年第4期7卷 344-350页

作者： Femando Miguel de Amorim Lino Diogo Cordeiro dias Renata Crispim Batista Eric de Souza Gil Iranaldo Santos da silva Lucio Angnes Faculty of Pharmacy Federal University of Goias Goiania 74605-220 Brazil Postgraduate Program in Environmental Engineering Federal University of Goias Goiania 74603-150 Brazil Institute of Chemistry University of Sao Paulo Sao Paulo 5509 Brazil

Technological development has led to the emergence of new substances with many different purposes generating a new profile of pollutants in waterways. Among these, endocrine disruptors, such as 17EE （17ct-ethinylestradiol）, are of great importance due to their wide application and harmful consequences to the environment, human health and animals. The inefficiency of most water treatment processes in withdrawing such substances poses a global concern for the development of effective and environmentally clean methods. The electrochemical remediation processes appear as a powerful and ＂green＂ alternative for waste removal of organic or inorganic pollutants from complex environments, such as geosphere and hydrosphere. The research focus in this field is mostly related to the optimization of electronic devices with higher （photo） catalytic efficiency, whereas the starting material remains based on metal and carbon conventional electrodes. In the present study, the anodic removal process of 17ct-ethinylestradiol at carbon cardboards was investigated in stationary and hydrodynamic conditions. The influence of pH and applied potential were evaluated, always taking into account the transposition of scale and environmental aspects. Thus, the principle of hormone removal showed to be strictly related to such parameters. It was observed that mild alkaline medium favors the anodic oxidation, whereas neutral and mild acid ones lead to higher adsorption at carbon surface. Also, when the applied potential was higher than 1.25 V, the electrochemical oxidation rate increased, and the adsorption was decreased. Furthermore, the removal efficiency of ! 7EE showed to be lower, the flow rate was higher.

The upland rice is grown in most Brazilian states. However, in many of them the yield obtained is low. The choice of cultivar more suited to a particular environment can contribute to increased productivity of this crop. This research aimed to evaluate the performance of a hybrid cultivar of upland rice (Ecco) and five conventional cultivars (BRS Monarca, BRS Primavera, AN Cambará, BRS Sertaneja and BRS MG Curinga) in two environments (Vilhena and Cerejeiras). The tests were conducted in the agricultural year 2010/2011. We evaluated the following characteristics: tillering, panicle number per unit area, number of filled grains per panicle sterile, mass of grains per panicle, 1000 grain weight, grain yield (kg·ha-1) and whole grain yield. There was no cultivar x environment interaction for all traits. Greater tillering, higher panicle number per area, higher productivity and yield of whole grains in the municipality of Cerejeiras were observed, while the highest number of sterile grains per panicle was obtained in Vilhena. The hybrid Ecco highlighted in relation to all other cultivars is in relation to tillering, panicle number per area and grain yield. The municipality of Cerejeiras is the most suitable for the cultivation of upland rice.
